Error "Attempted to access negative index of FVector.!

[PhdStudent2015]

I'm tried the provided example in the cogcomp-nlp readme and a got a wierd Error that could not figure out how to solve it. Please me.
My code :
`String text = "He went to Chicago after his Father moved there.";

        String corpus = "story";
        String textId = "001";
        AnnotatorService annotator = PipelineFactory.buildPipeline(ViewNames.POS, ViewNames.NER_CONLL);
        TextAnnotation ta = annotator.createAnnotatedTextAnnotation(corpus, textId, text);
  	    View mentionView = ta.getView(ViewNames.POS);
	    System.out.println("Pos Values: ");
	    mentionView.getConstituents().forEach(v->System.out.println(v));`

Sorry for the inconvenience.
Can you try the version "4.0.12" instead? (and let us know if you see the same thing?)

[PhdStudent2015]

Same error with version "4.0.12" and "4.0.0" ! My computer runs Windows 10 Entreprise.

[danyaljj]

Ah that might be it. Unfortunately, we're not fully compatible with Windows (yet).
